I have a problem with the Fronter 350, when I turn on the distribution, it starts to work on the image and always reports the error of the open door to the end, and in the distribution, I leave three blue papers

please help

Put some old paper, open door and block door sensor. Go to output check and manually run distributor. Look how it works. If all well try to make prints ( with opened door ) . You can see what is wrong there. Sometimes is enough to clean distributors to have better contact between distributor and paper.

The door sensor is not one sensor but two, One is in contact with the computer and one in line with the power supply. The one that is giving you trouble is the one connected to the computer. There are switches constructed for low power signal use around, but those used in the frontier is not. Exchange the switches and all works well again.
